I have been working on this for few weeks...and for the smaller plane for 4.5 years.
I figure a streamlined very lite BWB aircraft could do it..with 257 m2 of solarpanel area and 44 souls on board of which 40 people ( the passengers ) pedal for the pressurization.
Best rates the NASA has been able to absorb energy is 20% ( 200-250 watts/m2 ). Pedalling brings about 30 hp ( max ) more.
Take off and climb to 40 000 ft would take place by using precharged batteries ( about 180 kW ).
Plane sports around 50 to 1 C/L...and best range about 2000 km. It will not fly at nite but uses constantly all the energy the panels will create during the daylite ( 8-10 hours ).
Vne is at 300 km/h and cruise at 100-130 mph.
Aspect ratio is around 20 for the wing...prop disc area 11.3 m2. Span is little more than the late Boeing 747 has at 65 meters.
Construction is superlite composite ( foam-plywood-carbonfibre ). Empty weight without batteries 1150 kilos. Loaded/unloaded ratio is around 4 ( same as the Voyager ).
I am interested from any college or university in UK to work on this with me on the construction..preferably in southern England, but all aviation specialised colleges are in my interest. I am an architect by profession...I have a pretty good idea how the details and construction overall will look like..as I do about the aerodynamics of this blended wing body design.
Any interest on this kinda flyer ?
